Stopping plant virus could impact HIV prevention. A study by
Purdue
University
researchers to stop virus reproduction in plants could lead to new ways to prevent infection by human immunodeficiency virus (HIV) and similar organisms.
Cauliflower mosaic virus, which attacks a plant group that includes cauliflower, broccoli and cabbage, and HIV, which causes AIDS, use the same process to multiply in their victims’ cells and spread disease.
Botany professor Zhixiang Chen and his colleagues have found that cauliflower mosaic virus relies on the same protein complex to multiply in plants. He said the proteins in the host plants might be particularly important for these types of viruses, such as HIV, because if they are blocked, then the viruses can’t replicate.
